TensorFlow 2.5 Mac M1 - Installing problem compatibility with NumPy library / Conda env

I have a huge problem creating a conda environment with the new Tensorflow 2.5 optimized for M1 (Macbook pro-2020).

I followed those steps:

  1. install miniforge3 optimized for arm64 processor from https://github.com/conda-forge/miniforge
  2. then create a conda env on the terminal ("conda create --name tf25" and "conda activate tf25")
  3. After I followed the apple guide (https://developer.apple.com/metal/tensorflow-plugin/)

This is the result:

enter image description here

In the end, when I try to import the NumPy package there is an import error.

import numpy

During handling of the above exception, another exception occurred:

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy C-extensions failed. This error can happen for many reasons, often due to issues with your setup or how NumPy was installed.

We have compiled some common reasons and troubleshooting tips at:

https://numpy.org/devdocs/user/troubleshooting-importerror.html

Please note and check the following:

  • The Python version is: Python3.9 from "/Users/antoniosquicciarini/miniforge3/envs/tf25/bin/python"
  • The NumPy version is: "1.19.5"

and make sure that they are the versions you expect. Please carefully study the documentation linked above for further help.

Original error was: dlopen(/Users/antoniosquicciarini/miniforge3/envs/tf25/lib/python3.9/site-packages/numpy/core/_multiarray_umath.cpython-39-darwin.so, 2): Library not loaded: @rpath/libcblas.3.dylib Referenced from: /Users/antoniosquicciarini/miniforge3/envs/tf25/lib/python3.9/site-packages/numpy/core/_multiarray_umath.cpython-39-darwin.so

Reason: image not found

I already tried to:

I think there is a compatibility problem with the new TensorFlow an NumPy library, because until today I used the TensorFlow 2.4 in another conda env

Original error was: dlopen(/Users/ulto4/miniforge3/envs/python386/lib/python3.8/site-packages/numpy/core/_multiarray_umath.cpython-38-darwin.so, 2):

You need to install openblas:

conda install -c conda-forge openblas

This fixed the error and numpy works.
